在这部冒险男孩家庭片中,当英格兰最大的城堡被臭名昭著的犯罪老板（乔恩·坎普林饰，曾在《哈利·波特》中扮演食死徒）抢劫时，他和他的犯罪团伙却没想到要面对骑着越野自行车的两个男孩。
当男孩的母亲（安吉拉·迪克森（Angela Dixon），“永不放手”（Never Let Go））和竞速赛车手的父亲离开儿子回到旧金山旅行时，他们的“老派”父亲不喜欢在手机上度过的时光，反而使他们想起了激动或现实生活冒险。
命运的转折导致男孩发现了钻石盗窃案，但在此过程中，他们的父亲因犯罪而被捕，引发了一场与时间赛跑的竞赛。
When England's largest castle is robbed by a notorious crime boss (Jon Campling, Harry Potter's Death Eater), the last thing he and his criminal gang expected to be up against were two boys on BMX. When the boys mother (Angela Dixon, Never Let Go) leaves her sons with their Speedway racer father for a trip back to San Francisco, their 'old school' dad disapproves of their time on devices and instead reminds them of the exhilaration or real life adventure. A twist of fate leads the boys to uncover the diamond theft but in the process gets their father arrested for the crime. A race against time ensues. Can these boys use their dad's training to get him out of jail in time for his Speedway race. With twists, turns, laughs and outrageously fun plot, Adventure Boyz aims not only to entertain the whole family, but remind us all of the thrills and adventure we can all have away from a device.
